基于QFD/TRIZ的热透灸理疗仪创新设计

目的 为提升热透灸理疗仪设计过程中技术实施的可行性和用户需求的满意度，提出一种基于QFD和TRIZ集成的热透灸理疗仪创新设计方法。方法 分析QFD在产品设计中的不足，将TRIZ与QFD进行结合，构建两种理论的集成设计模型；通过对热透灸理疗仪设计特征分析，采用问卷调查、专家访谈等方法获取用户需求，得出质量要求与质量要素之间的层次关系；运用QFD法构建质量屋（HOQ），明确设计前期产品改进的重点方向，得出热透灸理疗仪设计的约束条件和工程因素矛盾；结合TRIZ理论描述其矛盾，并分析矛盾属性，利用相应的发明原理解决其创新设计时存在的矛盾冲突；最后基于矛盾的解决对热透灸理疗仪进行再设计。结论 结果表明，以QFD为基础、TRIZ为解决手段的设计方法提高了热透灸理疗仪设计的工程效率，可有效指导其创新设计过程。

Innovative Design of Hot Moxibustion Therapy Apparatus Based on QFD/TRIZ

The work aims to propose an innovative design method of hot moxibustion therapy apparatus based on QFD and TRIZ integration, in order to improve the feasibility of technology implementation and the satisfaction of users'' demands in the design of hot moxibustion therapy apparatus. The deficiencies of QFD in product design were analyzed. Combined with TRIZ and QFD, the integrated design model of the two theories was constructed. Based on the analysis of the design characteristics of the hot moxibustion therapy apparatus, the user demand was obtained by means of questionnaire surveying and expert interviewing, etc. and the hierarchical relationship between quality requirements and quality factors was obtained. QFD method was applied to construct the house of quality (HOQ), the key direction of product improvement in the early stage of design was clearly defined, and the contradiction between the constraint conditions and engineering factors of the hot moxibustion therapy apparatus design was obtained. Combined with TRIZ theory, its contradictions were described, and the contradictory attributes were analyzed. The conflicts in its innovative design were solved with the corresponding inventive principle. Finally, based on the contradiction resolution, the hot moxibustion therapy apparatus was redesigned. The results show that, the design method based on QFD and with TRIZ as the solution improves the engineering efficiency of the hot moxibustion therapy apparatus design, which can effectively guide its innovative design process.
